Oslo: DeepOcean has secured a riser installation contract for the Kristin and Heidrun platforms from Statoil.
The modification of these platforms is required in preparation of a possible tie-back from the near-by Maria-development in the Norwegian Sea that is operated by Wintershall. The offshore work includes the installation of risers as well as dynamic umbilical and cable.
The installation will be carried out by offshore construction vessel Edda Freya, with the newbuilding joining the DeepOcean fleet in the first quarter of 2016. The 149.8m long vessel has a 600 tonns AHC crane and can accommodate 140 people. Additional support will be provided by a light construction vessel from DeepOcean’s fleet.
Work will start in the third quarter of 2016, and includes the preparation of subsea infrastructure and installation of a dynamic control umbilical, a direct electrical heating (DEH) cable and optional change–out of a production riser on Kristin semi-submersible platform. A water injection riser will be installed on the Heidrun Tension Leg Platform.
“We are appreciative of Statoil again recognizing DeepOcean’s ingenuity and cost efficient solutions in times of strong cost focus across the subsea value chain.” says Ottar Mæland, DeepOcean’s evp Greater North Sea.
